“Wake windows” are a popular parenting concept, not a precise medical measure. Use them as a loose guide alongside your baby’s tired signs — yawning, looking away, fussiness — which matter more than the clock.
It’s the length of time a baby stays awake between one sleep and the next, including feeds and play. Wake windows gradually get longer as a baby grows.
No. They’re typical ranges drawn from general guidance. Healthy babies vary a lot, and your baby’s own pattern is the best guide.
Baby App PRO estimates the next sleep window from your own baby’s recent rhythm, not from age averages — and it all runs privately on your iPhone.
